Hello-
I am a long time apple user, and i have been looking for a certain kind of app for a while. I would like an app that lets you build a secret lair or safehouse type thing. Ideally, it would have nice graphics and a bit of challenge. I cannot find an app that does this. Doe anyone know of one like this?

Ps. 2 more things
1. It should not be an app where you cant do anything without playing and
2. I have already tried minecraft pe and survivalcraft, neither have the things i look for.

Thanks for your help in a search that has been going on for months!
